Task #1358

This issue is dedicated to validate the last changes made to manage the installation and the execution of TXM with our own embedded JRE rather than using the client JRE as before.
(You can see #989 for more information on what has been developed and researches done about this question.)

h3. Validation test

* optional: uninstall all Java JRE/JDK from your system
=> to check there is no installed Java, open a command line "cmd" console (Windows system) or a terminal (Linux and Mac system) and type "java". The console must say something like "unknown command" or "command not found".

* install the last TXM 0.7.7 beta 2 setup for your system from here: xxxxx
=> installer must not complain about Java installation
* run TXM
* go to "Help\About TXM\Installation Details\Configuration" and check that you have the 3 following lines:
** "java.home=..." line that must be as following according to your OS:
*** For Windows: "java.home=[TXM Install Directory]\jre" Directory]\jre\jre" where "[TXM Install Directory]" must be your TXM installation path.
*** For Mac OS X: "java.home=/Applications/TXM/TXM/jre/Contents/Home"
*** For Linux: "java.home=/usr/lib/TXM/TXM/jre/Contents/Home"
** "java.runtime.version=1.7.0_75-b13"
*** except for Mac OS X where the entry must be "java.runtime.version=1.6.0_65-b14-466.1-11M4609"
** "java.vm.name=Java HotSpot(TM) 64-Bit Server VM" for 64bit system and "java.vm.name=Java HotSpot(TM) 32-Bit Server VM" for 32bit system

* please provide your exact OS version and architecture (32bit or 64bit)
* please precise if you have uninstalled all Java JRE/JDK from your system before doing the validation test
